israel testing ‘extremely nasty’ weapon, page-54

So, to take your analogy a little further:

the police showed up, gave you the latest and greatest weapons and ammo and said they'd turn a blind eye to any action you saw fit as retribution. You have carte blanch to raze the whole neighbourhood. I mean, these other people live near the assailant so let's face it they're probably guilty by association and have it coming, besides who knows some may grow up and pose a threat to you in the future. Kill them all and let God sort them out. No one likes a punch in the nose.
